PROVO, Utah -- A woman and her unborn child died Tuesday afternoon, three days after being involved in a crash on Highway 40 in Utah's Wasatch County.

Shantell Young was driving with her baby's father, Macoy Young, when a car that turned out to be stolen, crossed lanes and crashed into their Audi Saturday, authorities said.

Shantell, 22, suffered multiple serious injuries, including brain injuries. Doctors were waiting for the swelling in her brain to go down at the time of her death. Macoy suffered multiple broken bones and doctors had to surgically repair his aortic artery.

The Utah Highway Patrol confirmed that the crash was fatal in a tweet around 3:45 p.m.
